A plastic glove when attached to a flask gives the system a flexible volume.See the illustration below. From a starting point of 257 mL at 22 °C,to what volume will the system change if the temperature rises to 137 °C due to the heating by the laboratory burner?

Since the plastic glove attached to the flask gives the system a flexible volume, we can assume that the pressure remains constant. Therefore, we can use the formula:

V1/T1 = V2/T2

where V1 and T1 are the initial volume and temperature, and V2 is the final volume at the new temperature of 137 °C.

Plugging in the values, we get:

257 mL / (22 + 273) K = V2 / (137 + 273) K

Solving for V2, we get:

V2 = (257 mL / 295 K) * 410 K = 357 mL

Therefore, the answer is D, 357 mL.
